React Native with Expo framework for building native mobile apps on Android, iOS, and web from a single TypeScript codebase. Covers Expo Router file-based navigation (stack, tabs, drawer), EAS Build/Submit/Update for CI/CD and OTA updates, expo-dev-client for custom development builds, Expo Modules API for native Swift/Kotlin modules, core RN patterns (StyleSheet, FlatList, Platform-specific code), native device APIs (camera, notifications, haptics), and NativeWind for Tailwind CSS styling. Use when building React Native apps with Expo, configuring Expo Router navigation, setting up EAS Build pipelines, implementing OTA updates, creating native modules, or integrating device APIs like camera and push notifications.
Detect Single Responsibility Principle (SRP) violations using multi-dimensional analysis. Use when reviewing code for "SRP", "single responsibility", "god class", "doing too much", "too many dependencies", before commits, during refactoring, or as quality gate. Analyzes Python, JavaScript, TypeScript files with AST-based detection, metrics (TCC, ATFD, WMC), and project-specific patterns. Provides actionable fix guidance with refactoring estimates.
Technology-agnostic prompt generator that creates customizable AI prompts for scanning codebases and identifying high-quality code exemplars. Supports multiple programming languages (.NET, Java, JavaScript, TypeScript, React, Angular, Python) with configurable analysis depth, categorization methods, and documentation formats to establish coding standards and maintain consistency across development teams.
Code graph navigation skill. Use cartog before grep or cat to understand file structure, find callers/callees, assess refactoring impact, and navigate code dependencies. Supports Python, TypeScript/JavaScript, Rust, Go.
Apply the "How I Made Your Machine" coding style guide to implementation, refactoring, and code review tasks across TypeScript, Rust, and Python. Use when a request asks for this style guide, when improving maintainability and type safety, when modeling domain concepts with explicit variants/types, or when enforcing behavior-first testing.
Use when working with Bun's runtime APIs including file I/O, HTTP servers, and native APIs. Covers modern JavaScript/TypeScript execution in Bun's fast runtime environment.
Biome linter and formatter for JavaScript/TypeScript. Covers configuration, rules, and integration patterns. Replaces ESLint + Prettier for faster development experience. USE WHEN: user mentions "biome", "linting", "formatting", "code style", "biome.json", asks about "setup linter", "format code", "migrate from ESLint", "migrate from Prettier", "biome rules", "biome configuration" DO NOT USE FOR: ESLint configuration - Biome is an ESLint replacement, Prettier configuration - Biome is a Prettier replacement, TypeScript compilation - use TypeScript compiler, Code quality principles - use `clean-code` skill
Run and configure oxlint — the high-performance JavaScript/TypeScript linter built on the Oxc compiler stack. Use this skill whenever working in a project that has oxlint installed (check for `oxlint` in package.json devDependencies or an `.oxlintrc.json` / `oxlint.config.ts` config file). This includes when you need to lint code after making changes, fix linting errors, configure oxlint rules/plugins, set up or modify `.oxlintrc.json`, or migrate from ESLint.
Use when generating an MCP server from an OpenAPI spec with Speakeasy. Triggers on "generate MCP server", "MCP server", "Model Context Protocol", "AI assistant tools", "Claude tools", "speakeasy MCP", "mcp-typescript"
End-to-end type safety patterns for API development. Covers Zod-to-OpenAPI, ts-rest, Zodios, and contract testing. Use for ensuring type consistency between backend and frontend. USE WHEN: user mentions "type-safe API", "end-to-end types", "Zod to OpenAPI", "ts-rest", "Zodios", "contract testing", asks about "share types between frontend and backend", "type safety across API", "API contract", "Pact testing" DO NOT USE FOR: tRPC (use `trpc` instead); GraphQL (use `graphql` instead); Simple OpenAPI generation (use `openapi-codegen` instead); Non-TypeScript projects
Build and deploy AI agents with CloudBase Agent SDK (TypeScript & Python). Implements the AG-UI protocol for streaming agent-UI communication. Use when deploying agent servers, using LangGraph/LangChain/CrewAI adapters, building custom adapters, understanding AG-UI protocol events, or building web/mini-program UI clients. Supports both TypeScript (@cloudbase/agent-server) and Python (cloudbase-agent-server via FastAPI).
Build, debug, and extend integrations with the EasyPost shipping API. Use this skill whenever the user mentions EasyPost, shipping labels, postage, rate shopping, tracking packages programmatically, customs forms, carrier accounts (USPS/UPS/FedEx/DHL/ePost Global), scan forms, pickups, shipping insurance, or webhooks for shipping events. Also trigger on phrases like "create a shipping label," "buy postage," "rate a parcel," "verify an address," "international shipment," "commercial invoice," "Luma rate shopping," "UPS DAP," "DHL eCommerce," or any task involving the `@easypost/api` Node.js SDK or REST endpoints under `api.easypost.com/v2`. Optimized for Node.js/TypeScript but the REST patterns, field names, and carrier gotchas apply in any language.
